FRYING GUIDELINES (All Models)

• Heat shortening to set temperature.

• Fry pieces of product that are about the same size together.

• Drain or wipe dry raw or wet foods to minimize splatter when lowering into the hot shortening.

• Keep shortening between the MIN and MAX lines. Shortening will expand when heated; do notfill the fry tank past the MAX line.

• Add fresh shortening as needed.

Fry Basket Guidelines

• Shake the basket gently to avoid splattering the shortening.

• Do not overfill baskets (see Recommended Basket Capacities below).

• Hang baskets on rear basket hangers when frying is complete.

• To help reduce batter buildup, dip the basket into shortening before loading.

DAILY FILTERING


Filtering Guidelines (All Models)

• Stand alone fryers are available in filter-ready and non-filter-ready versions.

• Battery interplumbing is available only on fryers equipped with KleenScreen.

• A cold fryer will not drain properly. Always filter shortening in a liquid state. The shortening underthe cold zone area will remain hard, even if the heat is on for a few minutes. If necessary, usethe cleanout rod to carefully stir the hard shortening to an area above the cold zone (Fig. 8)where it will melt.

• Filter shortening at least once a day (see Shortening Life on page 33).

Fig. 8

Filter-Ready Fryers (For Use With Mobile Filter Only)

• The Mobile Filter is covered in a separate instruction manual. Follow the instructions.

Battery Interplumbing (Only Available on KleenScreen Models)

A battery of fryers equipped with optional interplumbing connects the fry tanks to a common drain.Each tank has an individual drain valve. Only one tank can be filtered at a time. Instructions for theKleenScreen filtering system are covered in a separate manual. Follow the instructions.

Filtering Procedures (Non-Filter-Ready Fryers)

1. Shut down the fryer.

2. Slowly remove basket(s).

3. Open fryer door and attach the drain pipe to the drain valve.

4. Select a container that will hold all the liquified shortening and place it below the drain pipe.

5. If using a filter bag, tie it securely to the drain pipe. If a different filter medium is used, place itin the container.

6. Open drain valve carefully so the oil stream is directed through the filter. See FilteringGuidelines on page 31 for draining tips.

7. Flush out scraps and sediment in the fry tank with a small amount of warm shortening.

8. Drain the tank thoroughly and wipe clean.

9. Should it be necessary to clean the tank more thoroughly, see Cleaning on page 33.

10. Close the drain valve.

11. Pour the filtered shortening back into the fry tank.

12. Shortening level should be between the MIN and MAX lines.

HIGH LIMIT DEVICE (All Models)

If the shortening becomes overheated, a high-temperature device will close the gas valve andextinguish the pilot. Should this occur, the pilot will be unable to relight until the shortening temperatureis below 300°F (149°C). If the temperature is below 300°F (149°C) and the pilot will not relight, contactyour local Vulcan-Hart Service office.

DRAIN INTERLOCK (GRD and GRC Series)

Prevents the burners from operating when the drain valve is open.

SHORTENING LIFE (All Models)

Shortening life can be extended by following these guidelines:

• Do not salt foods over the fryer.

• Use good quality shortening.

• Filter shortening daily (at a minimum).

• Replace shortening if it becomes poorly flavored.

• Keep equipment and surroundings clean.

• Remove excess moisture and particles from food products before placing in fryer.
